- MVAJ101RA0802A Industrial Single Board
Description
The MVAJ101RA0802A is a high-performance trip/auxiliary relay module manufactured by GE Vernova / formerly Alstom Grid (or its predecessor brands). It belongs to the MVAJ series of
hinged-armature tripping relays designed for industrial protection and control applications. Despite some listings referring to it as a “single board”
or “industrial single board,” the core functionality is as a trip relay rather than a general-purpose single-board computer. For example, one
isting labels it as “Industrial Single Board Computers … Protection Relay” although this appears to be a mis-categorisation.
Feature And Application of MVAJ101RA0802A
| Feature |
Application |
|
From the available documentation for the MVAJ 05/10/20 series (which includes the “101” variant) and general references for this model, the following are the notable features:
-
High-speed operation with very little contact bounce, suited to circuit breaker trip coil operation.
-
Hinged armature design which enhances reliability and mechanical robustness.
-
Versatile configuration: available in hand-reset, electrical-reset and self-reset forms; the “101” variant is a self-reset type.
-
Dual burden configuration (low-burden and high-burden) selectable via external link: the high-burden option allows for e.g. 100 W burden for 40-60 ms before cut off to economised level.
|
Typical applications for the MVAJ101RA0802A (and the MVAJ series) include:
-
Direct operation of circuit-breaker trip coils in power distribution and transmission systems: the relay acts as the interface between protective relays and breaker trip mechanisms.
-
Industrial electrical protection systems where high speed and high reliability are required (e.g., substations, utilities, large industrial plants).
-
Control and signalling in tripping schemes: due to its self-reset or resetable features it can be integrated into automatic protection circuits and schemes.
